Unconscious state

Case (i) Japanese viral encephalitis of a 28-year-old woman. Symptoms unconscious for 19 days, left-sided hemiplegia, constant convulsive motion on the right side of the body, loss of all superficial and deep reflexes. Prior to the onset of this disease, the patient was reported to have almost regular dreams of being murdered by a group of people. Then she developed headache, fever and unconscious state. 

Most inhalants have no medical use. Exceptions are the anesthetic gases and amyl nitrite. Anesthetic gases slow the heart s pumping action, resulting in a drop in blood pressure. They also deaden pain and put surgery patients into an unconscious state. Amyl nitrite, a clear, yellowish liquid, relaxes the smooth muscle in the walls of the arteries. That relaxation dilates the blood vessels, reduces blood pressure, and increases the heart rate. 

The authors suggested that clonidine could have been responsible for the maintenance of her unconscious state.

The patient can experience psychotic disturbances which are exhibited by paranoid behavior, self-destmctive actions, random eye movement, and excitation. These are combined with physiological changes such as tachycardia, hypertension, respiratory depression, muscle rigidity, increased reflexes, seizures, and an unconscious state with open eyes. 

S.B. was a 63-year-old man who was brought to the emergency department in an unconscious state. He had apparently taken an overdose of his prescribed anticoagulant medication, resulting in a bihemispheric bleed that caused compression of the brain parenchyma. Neurosurgeons and neurologists who were called to evaluate determined that his condition was inoperable. 

Daily life is roughly classified into two items of in awake and at sleep. For the former, mental activities modulated by reason and emotion et al, are expressed by cerebrum for a conscious response. On the contrary, for the latter, because of unconscious state, autonomic nervous system activity is superior so that physical activities are expressed for an unconscious response. This is why the answer is put into unconscious response. Thus, measurement system developed at the present study if set at home would make possible to take data. 

Of course, Elizabeth Barlow drowned. The amount of insulin injected was sufficient to produce an unconscious state but probably not to cause death. Consequently, it is believed that her husband drowned her because she failed to die as quickly as he expected. It has been pointed out that had he left her overnight, she may have died or suffered irreversible brain damage while at the same time her body may have absorbed most of the injected dose thus leaving no evidence for forensic investigators to find. ... 

Narcosis Narcosis is a state of deep stupor or unconsciousness, produced by a chemical substance, such as a drug or anesthesia. Inhalation of certain chemicals can lead to narcosis. For example, diethyl ether and chloroform, two common organic solvents, were among the first examples of anesthesia known. Many other chemicals that you would not suspect can also cause narcosis. For example, even though nitrogen gas comprises 80% of the air we breathe and is considered chemically inert (unreactive) it can cause narcosis under certain conditions. Always work with adequate inhalation and avoid inhaling chemical fumes, mists, dusts etc. whenever possible. Use fume hoods and respirators as necessary. 

Arousal is a state of vigilance regulated by subcortical parts of the nervous system, especially connections between the nuclei of the amygdala, the hypothalamus and the brain stem. These unconscious responses prepare the body for action. 

Some comatose patients are unconscious for less than 2 hours, do not show signs of severe toxicity, and have few complications. In other patients, coma lasts from 2 to 24 hours, and symptoms are more marked. Patients with severe toxicity, including status epi -lepticus and malignant hyperthermia, may remain in coma for 1 day to 3 weeks. These patients often have respiratory or metabolic acidosis. Comatose patients are susceptible to aspiration pneumonia and rhabdomyolysis. Head injury and intracerebral bleeding should be considered as the cause of the comatose state. 

All three officers got up from Burns at the same time. The supervising officer stated that Burns looked like anybody who was unconscious he saw nothing out of the ordinary. Several minutes had passed after application of the second hold (there was a dispute about how many holds had been applied), at which time the officers discovered that Burns was not breathing and applied cardiopulmonary resuscitation. Burns, however, was dead.

This aspect of the Work is called the redemption of the personality, whereby the unregenerate aspects in the depths of our unconscious are evoked to visible appearance, brought into the unifying light of consciousness, and thereby absorbed from their state of separation back into the integrated personality. Jungian psychology calls this... 

Ketamine has analgesic activity that persists beyond the period of unconsciousness up to 1 h after injection. On regaining consciousness, the patient may experience a disconnection between outside reality and inner mental state (dissociative anesthesia). Frequently there is memory loss for the duration of the recovery period however, adults in particular complain about dis-Ltillmann, Color Atlas of Pharmacology... 

Is there a certain kind of anatomy that is most likely to mediate conscious activity Also, are there any kinds of anatomical arrangements that are unlikely to orchestrate the unified brain state we know of as consciousness There are likely to be important constraints governing what is suitable anatomy for underlying consciousness in contrast to what kind of anatomy is favorably suited for unconscious information processing. These constraints are important clues as to how different neurochemical circuits divide up the manifold tasks taken on by the CNS.
